Need help deciding how late I am

okay mommas or soon to be’s. 

I need help because I’m genuinely so confused ,  so my last period was November 23 , 2020 to November 27 , 2020 . my app says my period was supposed to start December 22 , 2020 and it didn’t . it is now January 27 , 2021 .. that is 38 days . but it’s been 2 months with nothing (December and January ) , from December 22 to January 22 it’s been 38 days . 

am I one or two months late !?
